Coulomb's Law PS2 Lab

PS2 - Coulomb’s Law Lab NAME_ Period

Purpose: Find relationship between distance and electric force.





Observations-
Force Diagrams:
Balloon without Wand : Balloon with Wand:


Data:

Distance Balloon Moved from Origin (Force)	Distance from Wand to Balloon (distance)	1/ distance	1/ distance 2

Graph:

1. Force (y-axis) vs. Distance (x-axis):

2. Force vs. 1/Distance

3. Force vs. 1/Distance2

Calculations:
1. Rewrite the straight-line formula from graph #3.

Hint: y =mx + b (y = variable on y-axis, m = slope of line including units, x = variable on line, b = y-intercept plus units)

Questions:
1. What is the relationship between electric force and distance?

Conclusion:
